Embodiment 1

[0010] Add copper hydroxide, soluble organic compound ethanolamine and soluble active agent polyethyleneimine respectively in water, and the relative ratio of their molar equivalents is 2:0.5:0.5, and heat the resulting solution or suspension to a reflux state to form a homogeneous phase solution, and then add an appropriate amount of water to adjust the copper ions in the resulting homogeneous solution to 3% to prepare a copper complex algaecide.

[0011] During application, put the above-mentioned copper complex algaecide into the water polluted by blue and green algae, after 24 hours, take a water sample, the maximum removal rate of algae in water is 49.2%.

Embodiment 2

[0013] Add copper citrate, soluble organic compound salicylaldoxime and soluble active agent quaternary ammonium chloride respectively in water, the relative ratio of their molar equivalents is 3:0.8:1, and the resulting solution or suspension is heated to reflux state to form homogeneous phase solution, and then add an appropriate amount of water to adjust the copper ions in the resulting homogeneous solution to 8%, that is, a copper complex algaecide is prepared.

[0014] During application, put the copper complex algaecide prepared above into water polluted by blue and green algae, and after 48 hours, take a water sample, and the maximum removal rate of algae in the water is 90.8%.

Embodiment 3

[0016] Add copper chloride, soluble organic compound glycine and soluble active agent polyethyleneimine respectively in water, the relative ratio of their molar equivalents is 4:1.5:1.5, and heat the resulting solution or suspension to a reflux state to form a homogeneous solution , and then add an appropriate amount of water to adjust the copper ions in the generated homogeneous solution to 15%, that is, to make a copper complex algaecide.

[0017] During application, put the above-mentioned copper complex algaecide into the water polluted by blue and green algae, after 108 hours, take a water sample, the maximum removal rate of algae in the water is 85.6%.

Abstract

The invention provides a preparation method of a copper complex algaecide and belongs to the environment protection field. Divalent copper ion compounds, organic complexes and active agents are added into water, the proportion is 2 to 4:0.5 to 1.5:0.5 to 1.5 according to mole equivalent ratio, the prepared solution is heated to reflux state so as to form homogeneous solution, at last water is added, and copper atoms in the solution is regulated to 3 percent to 15 percent to prepare the copper complex algaecide. The preparation method of the copper complex algaecide of the invention has the advantages of good algae removal effect, low amount and simple use and is provided with potential of large scale popularization.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to a preparation method of a copper complex algicide. Background technique [0002] As we all know, blue-green algae has become a major problem in the current environment and water quality protection, and the growth of blue-green algae has directly affected human domestic water. Since the end of May this year, cyanobacteria have exploded in the waters of Taihu Lake in Wuxi City, Jiangsu Province, forming a large number of algae blooms that have seriously affected the drinking water supply for residents around Taihu Lake. The cause of the algal bloom in Taihu Lake is due to excessive nitrogen and phosphorus pollutants discharged into the lake body, resulting in eutrophication of the lake water. Under suitable temperature and light conditions, blue-green algae can grow excessively. The toxins produced during the growth of cyanobacteria, the toxins released after the death of c...
